Paper Sensors Detect Fake Drugs

Aug-21-18 Inexpensive paper sensors able to detect counterfeit medications could help save lives and reduce the spread of antimicrobial resistance.

Developed by a team from Colorado State University, the paper-based sensor is coated with two different substances: nitrocefin and the enzyme beta-lactamase in the ‘detection zone.’ To use the device, the antibiotic in question is dissolved in water. That water is then added to the sensor, where the antibiotic will cause a color change in the paper if it is diluted.
